To all whom it may concemr Be 7 i known that I, ENooH HENDERSON,

a citizen of the United States, and a resithetable revolves past workmenstationed about the table to pick out the barren rock.

A deflector, which is termed a plow, is disposed above the table in thepath of movement of the material being sorted and upon reaching the plowthe material is swept from the tableeither tothe inside or to theoutside thereof. The plow or deflector, is sustamed in position inamanner to be readily and conveniently displaced where desired and lowerrings,

and whereby the inertia of the plow is efiect-ively utilized inpreventing accidental displacement'of the plow.,

-'Furthermore, in the preferred form of the invention, the position ofthe plow relatively to the feed chute is such that the material beingreceived and the material belng swept from the table will act onopposite sides of i the plow to counter-act the pressure at oppositesides. Also, the particular form of the plow in the preferredconstruction is characterized by'strength and simphcity, and re- 'sultsin an effective sweeping of the material from the table. g

' The invention will be particularly eX- plained in the specificdescription following.

Reference is to be had to the accompanying drawings forming apart ofthis specification in which similar reference characters indicate thecorresponding partsin all the views. A

vided, having a circular track 11 thereon, on

,which the circular table 12 in the form of a -the plow is arranged tosweep'the material from the table at the inner periphery of the.latterto a chute 16 which may'lead to a crusher or other apparatus orreceptacle.

The track 11 is formed with-flanges 17 at each side to receiveseeuringbolts 18, Fig. a. The track 11 has a concave depression 19 1n its uppersurfaceand an opposed annular groove or depression 20 is formed in theunderside of the table 12, whereby to constitute with the groove ordepression 20, an annular race for the balls 13. In practice, the balls13 are cast iron and are placed in sufiiclent' numbers to substantiallyfill the ball race.

Thetable 12 is made in the form of upper the lower ring 21 beingseparately formed and secured to the upper rlng or table top by bolts23, or the like. Both the upper and lower rings may be formed in anynumber of segments, there be ing indicated, (see Fig. 1), six segmentsin each ring, and the segments of the respective ring breaking joint.The lower ring 21 is the narrower and has side flanges 22 to receive thebolts 23. At the inner periphery of the lower ring 21, a dependingannular flange 21 is formed to exclude dirt from the ball race and toprevent the axis of the table from moving horizontally which mightresult in the displacement-of the table from its bearings. i

- The vtable 12 may be given motion 'by any sultable means. In thepreferred arrangement, a pinion 24' on m driven shaft 25 meshes with acircular rack 26 cast on the lower ring 21, the said shaft being drivenfrom any convenient source of power. The manner of forming the table 12with the upper and lower rings enablesme to employ cast iron and thesame is true of the track 11 and the ball bearings 13. At the same timeany renewal of parts of the table involves the minimum expense. Thecastings form- 'ing the table and track are rough castings ting theserough castings to be employed vantageously formed of a piece of timber.

On the said timber at the back or outer face thereon, a wear plate 27 ofsheet metal is secured to take the wear of the material coming from thechute 14, the said. plow being arranged above the table across the pathof movement of the material and oblique to the said path of movement andoblique to the chute 14:. On the face of the timber a shoe 28 isapplied, the same being longitudinally curved so as to present itsconcave side to the path of movement of the' material, as clearly shownin Fig. 1, in which figure the arrows indicate the direction of movementof: the material, it being understood that the table is turnedeont'ra-cloclnvise with the arrangement shown, but may be turnedclockwise with a reversal of the deflector. At the back of the shoe 28,between the same and the timber a sheet metalplate 29 is providedprojecting above the shoe and contributing to the strength thereof aswell as forming a wear surface for the front side of the timber.

The inertia of the plow or deflector is utilized in retaining the plowin position and the upper surface of the plow is adapted to receiveweights 30, 31. In the illustrated form of the apparatus, the plow issuspended by a series of chains, indicated at 38, said chains beingpreferably connected with the plow at both ends of the timber and anadditional chain at the end of the curved shoe 28. The chains permit theplow 'to be adjusted at any desired distance from the surface of thetable 12. There may also be employed guys or tie chains 3%, 35 securedto the plow near each end and fixedly secured at theopposite ends'to anyconvenient fixed men'ibers or supports. I have shown eyes 36 on the plowto receive the chains 33, there being provided a shackle 37 on the plowat one end to connect with the chains 34, and an eye 38 near theopposite end. of the plow to connect with the chain 35. I prefer toposition the plow or deflector 15 adjacent to the delivery chute 14: sothat the material will be carried practically through a complete circlebefore being discharged. Also, in this way, the pressure of the materialbeing carried against the front of the plow will be largely counter-.

turnbuckles 40 or other means for effecting adjustment. Having thusdescribed my invention I claim as new, and desire to secure by LettersPatent 1. An apparatus of the class described,

including a table' in the form of 'a ring and mounted to turn on itsownaxis, means to give a traveling motion to said table on its axis,means to deliver material to the table, and a deflector extending overthe ring at,a side thereof across the path of movement of the materialcarried by the table, and adapted to sweep the material from the tableover a peripheral edge thereof, said deflector comprising a beampresenting a top surface adapted to receive weights, the front face ofthe beam being longitudinally curved, a

shoe secured to the face of the beam and ;path of movement of thematerial in front of the chute and oblique to the said path of movementof the material.

3. An apparatus of the class described, including a table in the form ofa ring, means to give a turning movement to the said table on its axis,a chute for delivering material to the table at one side of the ring,and a deflector positioned at the upper side of the said table andextending across the path of movement of the material in front of thechute and oblique to the said path of movement of the material, the saiddeflector presenting its concave side at the front to receive thecontact of the material carried by the table, the back of the deflectorbeing disposed toward the chute to receive the contact of the-materialdischarged by the chute.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ENOCH HENDERSON.
